Racha Noi Island is located further south than Racha Yai Island, and like Racha Yai, it is a dive site with very clear water. From November to April, the points on the west side, north tip, and south tip of the island feature dramatic underwater landscapes with large rocks piled on the seabed, reminiscent of the Similan Islands. Divers may often encounter manta rays, spotted eagle rays, and whale sharks, making this site suitable for intermediate to advanced divers who enjoy both topography and big marine life.
The east side of Racha Noi Island has calm bays with white sandy areas scattered throughout, making it perfect for beginners or divers returning after a break to enjoy a relaxed dive. Leopard sharks resting on the sand and opportunities for macro observation also make this side very enjoyable.

Banana Bay is located on the east side of Racha Noi Island. Within the bay, gentle slopes of pure white sand range from 5m to 30m, with scattered corals and rocks, making it a relaxing dive site. Schools of Glassfish gather around the rocks and corals, creating beautiful scenes under the sunlight. During dives, you may encounter large schools of barracuda or even turtles. Suitable for beginner courses, licensed diving, and fun dives, this site is an all-around diving spot.

Marina Bay, a large bay on the west side of Racha Noi Island, has shallow areas around 10m covered with branching and mushroom corals where colorful fish swim energetically. Further offshore, around 25m, large rocks are piled up, allowing divers to navigate through the gaps using neutral buoyancy. In areas with currents, large manta rays may gracefully swim overhead. Macro creatures like Sea Moths, Damselfish, and Pipefish can also be spotted, but their camouflage makes it a challenge. Depending on your skill level, you can enter from the inner or outer bay, offering flexible diving experiences.

Racha Noi Bay, located on the southeast of the island, features the only pure white beach. Divers can enter from the shallow bay and explore around the small islets protruding from the beach. In shallow waters (5-10m), beautiful branching coral formations give way to white sandy slopes. Large moray eels and porcupinefish hide in rock crevices, while garden eels and eagle rays inhabit the sand. Around the islets, the terrain becomes more dramatic with piled rocks, and manta rays may appear in gentle currents. This site offers the chance to encounter big marine life.

South Tip is a hidden pinnacle on the southern side of Racha Noi Island. High chances of encountering big fish such as Giant Trevally, barracuda, and large manta rays exist, but strong currents require solid diving skills. Divers typically enter from above the current and follow the guide to the hidden pinnacle, where they can wait for big marine life while using the rock to block the flow. The pinnacle's surface is carpeted with colorful soft corals, offering rich macro and reef fish opportunities.
